摘要

哺乳动物肠道α-葡萄糖苷酶存在于麦芽糖酶-葡萄糖淀粉酶（MGAM）和蔗糖-异麦芽糖酶（SI）复合物中。在这里，我们使用基于Flag标签的亲和层析从人胚胎肾293 （HEK293）细胞中纯化重组人MGAM和SI。在pH 6.0和37℃的稳态动力学分析表明，MGAM和SI的麦芽糖酶活性高于蔗糖酶和异麦芽糖酶活性。

Expression in HEK293 cells, purification, and characterization of recombinant human α-glucosidases.

In mammals, intestinal α-glucosidase exists within maltase-glucoamylase (MGAM) and sucrase-isomaltase (SI) complexes. Here, we purified recombinant human MGAM and SI from human embryonic kidney 293 (HEK293) cells using Flag tag-based affinity chromatography. Steady-state kinetic analysis at pH 6.0 and 37°C showed that the maltase activities of MGAM and SI were higher than their sucrase and isomaltase activities.
